IMPROVEMENT-IN COMPOUND RAILS.

Specification forming part of Letters Patent No. 222,498, dated December9, 1879; application filed September 24,1879.

To all whom it may concern.-

Be it known that I, WILLIAM JENNINGS HOLMAN, of Fort Wayne, in thecounty of A1- len and Stateof Indiana, have invented anew and ImprovedCompound Bail for Railroad- Tracks, of which the following is aspecification.

The invention relates to three-part rails so formed in passing throughthe manufacturingrolls that they will require no other device,appliance, or attachment. to make perfectly secure rails than to placethem together and spike them to the cross-ties.

The invention consists inthe construction and arrangement of parts, ashereinafter described and claimed;

Figure 1 is a sectional elevation of the compound rail, taken throughthe line w m, Fig. 3. Fig. 2 is a sectional elevation of the rail, takenthrough the line y y, Fig. 3. Fig. 3

through the line 2 2, Fig. 2. Figs. 4 and 5 are detailed views of a stopfor locking the parts of the rail againstlongitudinal movement upon eachother. 7

In outward form my improved rail resem- The rail is formed in threeparts-a cap bar,

tral line of the under side of the cap-bar A is formed a stem, D, havingflanges E upon the opposite sides of its lower part. The lower surfaceof the side parts of the cap-bar A is horizontal, and the spaces betweenthe said side parts and the flanges E are in U form, as shown in Figs. 1and 2.

The side bars, B O, are made with vertical outer sides, in line with thevertical sides of the cap A. The upper edges of the side bars,

and upon the inner sides of the upper edges of the said sidebars, B O,are formed flanges F, which fit into the spaces between the shoulders ofthe cap A and the flanges E. The

flat, to rest upon the cross-ties of the track,

and have flanges Gr formed along their outer sides.

Along the inner side of the lower edge of the side bar, 0, is formed athick flange, H, having a tapered groove, I, formed in it to receive theflange J, formed upon the inner side of the lower part of the side bar,B. Upon the lower side of the flange J is formed a shoulder, K, for thelower part of the flange H to abut against, as shown in Figs. 1 and 2.

With this construction the compound rail has a flat base to rest uponthe ties, and the three parts fit snugly upon each other, and are firmlylocked together, so that the compound rail can be spiked to the ties inthe same way as a solid rail, and will require no further fastenin g tokeep its parts together in engagement with each other.

The flanges H J should be made of such a thickness with respect to eachother that the two side bars may be of about equal weight and strength.

In each flange E of each cap-bar A is formed a notch, L, to receive thehead of a stop-pin, M. The stems of the stops M are inserted from theinner sides of the side bars, B O, in holes N, formed in the said sidebars, B C, so that the outer ends of the said stems may be flush withthe outer sides of the side bars, B (J. The stops M are designed toprevent the cap-bar A from being moved longitudinally upon the sidebars, B G, by the-wheels of pass ing trains.

I am aware that a compound railroad-rail has been constructed of threelongitudinal parts-to wit, a cap bar or rail and two side bars havingbase-flanges; but in such case it has been necessary to connect the sidebars by means of transverse bolts, in order to prevent themspreadingapart, even when spiked to the tie; whereas in my invention theinner base-flanges of the side bars are respectively constructed withrecess and tenon and shoulders, of such form that the parts of the railin= terlock, so that tie-bolts may be dispensed with, and said partsheld in due relation by means of spikes alone.

2. In a compound railroad-rail, the stops M in the side bars, B G, toengage with notches L in the flanges E, substantially as herein shownand described, to prevent longitudinal movement of the cap-bar A, as setforth.

WILLIAM JENNINGS HOLMAN.
